Description: Cardiothoracic surgeon Oh Yeon-joo's (Han Hyo-joo) father mysteriously went missing while writing the last chapter of his webtoon "W". Yeon-joo goes to his office and is shocked to see a scene of the dying Kang Cheol (Lee Jong-suk), the main character of W, on her father's computer. While reading a note left behind by her father, a hand from the monitor pulled her in and she finds herself on the rooftop of a building next to a bleeding man. She manages to save him and realizes that the person she saved was Kang Cheol. Yeon-joo later discovers that she can only leave the webtoon based on Kang Cheol's change in feelings. When that happens, the words 'to be continued' will appear and she will teleport back to the real world.
